My LO's first immunization was the 6in1 vaccine (Infanrix). But I found out that my health card shoulders only the 5in1 and if I want the 6in1, i have to pay for it. My question is (may sound trivial, but I just want to be sure), is it ok to give my LO the 5in1 even if his first one was the 6in1? The difference between the 2 is the HepaB vaccine, which btw is given in HK at 6mos.

Any thoughts will be appreciated.
